Across TCGA pan-cancer cohorts, KCTD9 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KCTD9 data layer compared with 22 for mass-spec protein and 5 for mass-spec protein.
The strongest signal is observed in adrenocortical carcinoma (ACC), where higher KCTD9 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated KCTD9 expression acts as an unfavorable survival marker.
ACC, ESCA, and UCEC are the cancer types where KCTD9 Mutation most reproducibly stratifies survival.
